Answer:
2=300 4=600 6=900 8=1200
150x=y
Step-by-step explanation:
On the graph we can visually see that there points on 300,600,900, and 1200 for serving of 2,4,6, and 8 respectively, So we input those numbers in the blanks for the number of Calories (Y).
As for the equation we are told:
Y = the number of calories
X = the number of servings
We need to figure what number times X will give us Y or, in other words, what number times the number of servings will give us the number of calories.
The first thing to note is that the amounts are increasing by 300 for every additional serving on the graph, but the number on the amount of servings are also going up by 2. This tells us that when the number of serving go up by 2, the number of calories go up by 300.
If every 2 additional servings increases the calories by 300, then half of 2 servings (or 1) should increase calories by half the amount.
300 divided by 2 equals 150, meaning 1 serving would increase the number of calories by 150. Because the increase in calories appears to be consistent with the number of serving, we can assume that calories will always increase by 150 for every serving.
In other words, the number of calories will always equal 150 times the number of servings or Y=150x
